Mine is already 260k. Now using Fully Synthetic 5W40 Mullerol. Change into that a couple of years ago, using FS Idemitsu 5W40 for years but engine vibration getting stronger and stronger. Lose of power a bit even after throttle body wash, etc. A bit fed up.
Since changing to this engine oil, it smoothen the vibration alot. Butter smooth acceleration. Power came back. Never realise just changing an engine oil that is suitable can makes such a big difference. Been using the oil since then. Gave this car a 2nd life extension.
Last time I get good price on Idemitsu (no more) and the mullerol almost double the price. I usually change every 6K (high mileage drive), coz Idemitsu FS seems to be losing properties at 7K, reduced power, etc.
Now due to the double price and the performance of Mullerol, I increase the mileage to 8K and surprisingly for me (after years with Idemitsu), at 8K, it seems to get even smoother and strong. Still I change it out at 8K mileage. I am a sucker for fresh oil to keep engine clean for years.
Have a tracked record of still maintaining engine in tip top conditions for a 20 years, 16 years and 14 years old rides. Spend a lot of car maintenance tho coz I don't drag things out unless pocket empty.
Try proton petronas oil FS.
Usually near 9000km only feel rough.
Using since day 1.
230k km. Changed my 3rd timing belt last week.
Still going strong. 2015 model
Spend alot this year to repair.
Now thinking wan repair minor leak at my flywheel or not
